Problem upgrading workspace to 3.5 [message #497152]

Hi,

I just downloaded the most recent build of Eclipse (Gallileo), I was previously using 3.4 and all was fine. The project I'm working on was originally created in an even earlier version (probably 3.3. but I don't remember). Anyway, I opened up my workspace in the new one and in my project (Java Web Project), I get this under my source directory.

Error: no label provider for org.eclipse.jst.servlet.ui.internal.navigator.Com

Now I'm assuming this has to do with the part that let's me browse the Java libraries that are used in this project, because that's missing, and I kind of need that in order to be able to attach sources and things like that. I've found no info on this. I tried rechecking the project out from source control but it's no good in this version. Creating a new project works fine but that's not really an option here. Anyone seen this before?

Possibly the version of Galileo that you downloaded doesn't have all the same
features as the previous version you were using. Did you download the J2EE
version of Galileo, or just the Classic?

I have precisely the same error message in the explorer view as Matt Rossner. In addition, I have a meaningless Error in the Problems view which has Path empty, Location "Unknown", and Type "Validation Message".

My Eclipse version is J2EE installed from eclipse-jee-galileo-SR1-win32.zip.

I'd suggest posting a question to eclipse.webtools or one of that forum's
subgroups. It sounds like some JST component is not initializing properly.

Also, check the error log (not the problems view) to see if there is any more
information. And look at the configuration (under the Help menu) to make sure
you are running Eclipse on a 1.5 or 1.6 JVM - if you run on 1.4, it will still
start up and mostly work but some components won't be able to load.

I'm running 1.6 and I checked the log. There are some stacktraces but it's rare to not find stacktraces in the log. That said I don't think they have anything to do with the error I'm seeing in Eclipse but maybe I'm wrong. Although I didn't see the webtools forum. I probably would have posted directly there. I'll do that now as it is a web project.
